Shares in junior precious metals miner Silver Sun Resources Corp. spiked 10% on Friday after becoming the sole owner of the Cherry Hill Mining Company, a fellow Californian gold miner. The Vancouver company's stock is up just short of 50% on the TSX-Venture exchange in 2011. Silver Sun is in the final stages of development of its gold project in Yreka, California and engaged in an on-going work programme in Mexico's prolific Zacatecas silver district and at a newly-acquired silver project Yoreme in Sonora state.
